NK Series

Frameless Low Cogging Servo Motors

NK-Series frameless servo motor kits are innovative and optimized, enabling the complete integration of a low-cogging direct drive servo motor within a mechanical system.
Available with 230/400VAC windings, power ratings to 34kW and speeds to 15000 min-1.

The NK servo motor kit is an innovative and comprehensive approach enabling the complete integration of the motor in a simplified mechanical system. This approach ensures that the size constraints of the machine are utilized to maximum effect. This delivers a more accurate, reliable and robust solution than traditional construction methods.
A complete range of products is available to meet the design needs of many different mechanical systems in a host of different applications. Other more bespoke adaptations can be developed upon request.
